I have a 96 4dr. Plymouth neon 2.0L SOHC.
I've re-soldered the little pins in the cluster twice now. After each re-solder the cluster would work for a few days. But then it went back to only working 50% of the time. Could it be something else? Like the sensors maybe? If anyone knows please let me know. Thanks!

No sir. What did you think I meant? Dealer? Ha! I can't go to the dealership and ask for a brand new cluster for my '69 Chevy, I have to get it aftermarket! They don't make stuff like that for our neons...
